COMBlNED OPERATING TABLE AND LOUNGE.

SPECIFICATION forming part of Letters Patent No. 357,688, dated February 15, 1887.

I Application filed April 22, 1884. Serial No. 128.894. (No model.)

To all whom it may concern-.-

Be it known that we, J AMES POOLMAN and FRANK R. MARKS, citizens of the United States, residing at New York, in the county and State of New York, have invented a certain new and useful Combined Operating Table and Lounge, of which the following is a specification.

Our invention relates to improvements in lounges designed especially for the use of surgeons and physicians; and it consists in an operating-lounge adapted to serve the purpose of a table, which can be elevated to any de sired height or be adjusted to any position or inclination required by the operator.

In the accompanying drawings, which serve to fully illustrate our invention, Figure l is a side elevation of our improved operatinglounge, partly in section, showing the upper portion of the same elevated. Fig. 2 isa transverse section of the same. Fig. 3 is a perspective view of the mechanism for elevating the upper sections of the lounge. Fig. 4. is a side elevation of the upper end of the lounge, showing the adjustment of the same; and Fig. 5 is an end view thereof.

The lounge proper consists of three frames, arranged one upon the other, a representing the stationary or base frame, mounted on legs and provided with casters; 1), the second or intermediate frame, which is connected by levers and a central guide-rod with the base-frame (0. whereby it is elevated from the base-frame and supported either in a horizontal or in an inclined position; and c, the upper or top frame, which is hinged to the intermediate frame, and is capable of several independent adjustments.

Into the side bars of the base-frame isjournaled a rod, 6, having formed on it right and left hand screw-threads, onto which are fitted nuts ff, with corresponding screw threads. To these nuts are pivoted one end of togglebars 9 g, which bars cross each other and are pivoted at their opposite end to the loose sleeves hi1, arranged 011 a rod, 2'. j j are levers, which are bent on an angle, and are connected together by the rod 1 at their lower end and by a similar rod, 70, at their upper ends. At the point Z these levers are pivoted by means of a pin, m, to the side rails of the base-frame. On each end of the rod is provided a friction-roller, a, on which rollers the intermediate frame, I), rests.

Centrally connecting the side rails of the base-frame a is a bar, 2, which serves as a guide-block for the vertical rod g, which is pivoted at its upper end to a hanger-plate, s, secured to the under side of the intermediate frame, I). As the frame I) and its, connected part-s are raised or lowered, the rod 1 works up and down in the guideblock and prevents any tendency to displacement or unsteady mo tion of the upper frames. This rod forms also a pivotal support and axis for the frame I) and connected parts when but one end of the upper frames are raised and the lounge is adjusted in an inclined position.

The rollers a travel to and fro on the under surface of the frame I), and their movement is limited by suitable projections or blocks 0 on the frame.

To prevent the frame I) from becoming displaced or lifted off of the rollers n, bent horizontal bars a are secured to the under side of the frame I), so as to hang below the rollercarrying rod 70.

The operation of elevating the upperframes is as follows: To the square end of the screwrod 0. thatprojects beyond the side rails of the base-frame, is fitted the crank a", which by turning rotates the rod 0, causing the nuts ff to recede from each other, carrying with them the toggles g and sleeves h, and turning the bent levers on the axial pin m, which, as they assumea vertical position on their pivot, lift the frame I) and connected parts. In order to elevate the upper part of the lounge to the horizontal position shown in Fig. 1, both screw-rods must be operated. If an inclined position is required, of course but one rod is rotated. The upper frame, 0, which is provided with cushions. is hinged at one side to the side rail of. the frame I), as shown in crosssection, Fig. 2, at a. The opposite side is capable of being raised, as shown in same figure. This elevation of the front portion of the hinged frame I) is accomplished by an independent device, as follows: Into the end rails of the frame b isjournaled a rod, 1;, having right and left hand screw-threads,on which are fitted correspondingly screw-threaded nuts w, to which are pivoted one end of levers x,

the opposite end of which is pivoted to one of the under rails of the upper or cushioned frame, a. By applying the crank l to the projecting end of the screw-rod o and rotating it, the front of the frame a is elevated, as shown in Fig. 2.

The upper frame, 0, which, as before mentioned, is connected by hinges at its back to the intermediate frame, b,is composed of three sections, a, a and a, each of which is provided with a cushion. The main sections a and a, which form the body portion of the lounge, are connected together by hinges b, which open upward. The third section, a forms the head-rest. This consists of a frame having an elevated cushion hinged thereto, so as to be capable of anindependent adjustment when desired. The side bars of the sections a" and (dare similarly cut away, as seen at c, Fig. 5, to form a rabbet joint, so that the section a slides upon the section a and when drawn out, as shown in dotted lines, Fig. 4, the length of the lounge is increased to suit the operator.

In the side bars of each section is provided a horizontal slot, 11. A rod, 6, passes through this slot, and its projecting ends are screwthreaded to receive the thumb-nutsf. After the section a has been extended to the desired point it is secured or clamped in position by turning one of the thumb-nuts up tightly to the side bar. The cushion g of the head-section a is mounted on a frame, h, which is hinged at its front edge to the frame a. To the under side of the cushion-frame 71/ is pivoted or hinged a bar, i, adapted to engage a notched bar, j, arranged on the frame a. By this means the frame It, with its cushion, may be adjusted at any desired inclination, as seen in Fig. 1. To the under side of the section a is hinged a similar bar, 7;, which engages with a notched bar, Z, arranged on the top part of the intermediate frame, I), and enables the section a of the upper frame, with its connected head-rest, to be elevated, as seen in Fig. 4.

As the frame I) and its connected parts are elevated from the base-frame a, its center is steadied bythe rod q, and any lateral movement on the rollers is prevented by the guiderails m on the under side of the frame, against which the rollers may impinge. If preferred, however, a groove may be formed for the rollers to travel in.

\Vhat we claim as new, and desire to secure by Letters Patent, is-

1. In an operating table and lounge, the combination of a stationary frame, an intermediate movable frame connected thereto by levers carrying rollers on which the said frame rests, and an upper and movable frame hinged to said intermediate frame, as and for the purpose set forth.

2. The combination, with the base-frame a and movable frames 1), rod 0, toggle-bars g, levers j, and rods 1' k, of the guide-harp on the base-frame a, and rod q, pivoted to the frame I), as and for the purpose set forth.

3. Theeombination,withthebaseframeand movable frame, of the right and left hand screw-rod 0, nuts f, toggles g, connecting-rod i, bent levers j, connecting-rod k, with rollers n, hangers s, with pivoted rod (1, and guideblock 1), all arranged and operating as set forth.

4. The combination of the base-frame a, intermediate frame, I), and hinged frame 0, having hinged sections a and a and sliding section at, having slotted side bars, (1, rod 0, and thumb-nuts f, as and for the purpose set forth.

5. The combination of the hinged sections a and a, sliding section a, having hinged head-rest g, ratchet-bar j, and bar i, all arranged and operating as set forth.
